so we always use the latest in the classpath

RSS is becoming outdated, JSon is a better example

- Now using namespace, much simpler (11 lines instead of 27)
- Just a minor issue with:
<bean class="org.springframework.web.servlet.view.JstlView">
	<property name="url" value="" />
</bean>
(should investigate later if we can remove “url” attribute

Spring MVC should server static resources (*.html, ...) located in src/main/webapp instead of returning "404 Not Found"

see: https://jira.springsource.org/browse/DATAJPA-292

Transactions should be on the root application context (or Hibernate will not be able to persist entities)

In that way we don't need a dedicated config file for the Service layer

see https://jira.springsource.org/browse/DATAJPA-292

(feedback from Oliver Gierke)

renamed profiles and removed unnecessary@DirtiesContext annotation so the Test suite now runs in 40% less time
